Description

The current implementation forces users to restart the service if any of the configurations have been updated.

However some of the services support reloading the configuration parameters during run-time which does not require restart of the service.

This behavior should be driven by metadata defined in configuration files.

  <property>
    <name>foo-bar</name>
    <value>0</value>
    <supports-reload>true</supports-reload>
  </property>
